Start out by sending party invites, printed up to look like movie tickets. Make sure to have a zombified ticket-taker at the door to take admission tickets. Don't forget classic move snacks like popcorn, soda, and Goobers to make the theme complete.
Provide ballots with each guest’s name listed and have party goers vote for their favorites. Be sure to award prizes for the a first, second and third place winners.
Once everyone has had a chance to see all the guests, collect the ballots. Figure out the winner and award a prize (and an Oscar trophy, of course!) before everyone leaves!
